You are COMPLETELY correct! The same goes for radiators, intercoolers, oil coolers, transmission cooler, heater cores, etc. There are some paints that are supposed to transfer heat better, but even those don't transfer heat as well as aluminum/brass....not even close.how many of you folks are painting the condenser for your a/c. finding it better not too. many of you folks already know this but for you folks that don't paint it.
Correct. Can do. I do know most of the time it blows about 34-38 degree air when I have driven it. Can’t say what the outside temp was though.your car is stock a/c correct. it is not aftermarket. when summer comes around can you take a temp reading at the input side and the output side. would like to know your temp drop.
Hmmmm…… I looked at that link. I have quite a bit of experience with both epoxy paints and with radiators/intercoolers/oil coolers/etc. Here are my thoughts, both good and bad. Epoxy is a pretty good insulator, but .002" thick sounds good, though that low of a film thickness is very, very difficult to achieve with an epoxy, even a very low solids (aka high VOC) epoxy. If the epoxy is filled with copper, silver or gold AND can be applied very, very thin, it would probably have decent heat transfer. I'm a little skeptical of the claims made by Dewitts.It's true that most paints, especially heavy coats of enamel, will do more insulating than heat shedding. However, there are paints with both high emissivity and conductivity. These also may not increase cooling, but at least do not hinder it. Uncoated aluminum or brass will eventually gather a layer of oxidation, and that oxidation can provide thermal insulation. After that happens, the properly coated radiator will likely start to look better for heat transference. Black Ice aluminum radiator paint, for example, doesn't claim to increase the effectiveness of a radiator. But it does claim protection without affecting heat transfer. https://www.dewitts.com/products/blackice
